In this step we have four pieces to solve. First choose a color to begin with. I chose white in this guide. For this time, choose the white as well, so the images along the solution will be relevant to your solving process. In addition, it is best to start with the white/yellow colors as they are the easiest colors for quick recognition which is important for speedsolving.

Important! The center pieces are part of the core and subsequently cannot move relatively to each other. For that reason they are already "solved". The solving process is actually bringing all corner and edge pieces to the "already solved" center pieces (meaning there are only 20 pieces to solve out of the 26). For example, the blue center piece will always be opposite to the green center piece (on a standard color-scheme cube). It doesn't matter how hard you will try scrambling the cube, it will just stay that way.
The most important part in the manufacture of a Rubik's cube is designing the mold for the various pieces. A mold is a cavity carved into steel that has the inverse shape of the part that it will produce. When liquid plastic is put into the mold, it takes on the mold's shape when it cools. The creation of the mold is extremely precise. The cavity is highly polished to remove any flaws on the surface. Any flaw would be reproduced on each of the millions of pieces that the mold will produce. In the manufacture of the cube parts, a two piece mold is typically employed. During production, the two mold pieces are brought together to form the plastic part and then opened to release it. The tool includes ejector pins that release the molded parts from the tools as it opens. All the parts are molded with auto gating tools that automatically remove the parts from the sprue as it is ejected. The molds are also produced with a slight taper, called release angle, which aids in removal. Finally, when molds are designed, they are slightly bigger than the pieces that they ultimately will produce. This is because as the plastics cool, they shrink. Different plastics will have a different shrink rate, and each tool must be specifically designed for the material that will be used.
Using the LEGO Camera support, attach the camera.  The small black lens of the camera should fit between the two LEGO beam supports.  Secure the camera in place to the LEGO supports with some electrical tape.  This is a good time to make sure that the camera is position to be able to capture the entire Rubik’s cube.  You can take a test picture with the raspistill command
Rubik’s Build It, Solve It is similar to the conventional Rubik’s block, but with a twist. This block includes each the tools, bits and directions kids need to be able to construct a Rubik’s Cube of the own. After this block was assembled together, there’s an education booklet (it’s’s 10-pages in duration) which will direct you through the procedure for solving the Rubik’s Cube (eventually). Here, you’ll find everything from identifying the areas of the block to solving fundamental puzzles. With this toy, kids will be provided a slow and continuous introduction about the best way best to use the block and progress to harder struggles. Rubix Build
